Hi Gino,
	I don't have any up to the minute information, but I do have the
Advisory Committee on Dangerous Pathogens ( ACDP ) report on '
Precautions for work with human and animal Transmissible Spongiform
Encephalopies'  ( UK  1994 ). Their recommendations for disinfecting non
autoclavable ( if that's a word ) surfaces is to use sodium hypochlorite
( 20,000 ppm ) for one hour. However as this is fairly corrosive for
metals and some surfaces, 2M sodium hydroxide can be used as an
alternative. For the very few times we have had a CJD case we used the
sodium hydroxide method.  This report also states that phenol is
ineffective in decontaminating formalin treated tissue and should not be
used. The recommendation is to treat formalin fixed tissues with 96%
formic acid for one hour.
	The publication is available from the HMSO offices in London, so
if you need the address let me know. The guidelines may be different in
Canada of course, and there may well be more up to date information
available.
		Hope this helps,

Hi,
Does anyone know of a decontamination procedure for benches or cryostats
after CJD exposure. Also, is there anyway to treat tissues with CJD?
We know of the phenol/formic acid method.
Are there other effective methods???????

Thanks in advance,
